Take a look at the overall picture, i.e. credit score, debts etc.. to make a decision.

I'm new as well congratulations on you're first property me and my fiance was going to start a real estate business but she has cold feet so i already have a LLC she the one who has the 820 credit score and I'm getting mine back in order we both have one property each i just loss my contract for my business so I'm thinking about using the equity from my home or turn my home it a bordering house just need some mentoring 

Is there a benefit to foreign national loans for a US citizen with a US credit score (the 791 I mentioned in the original post is my American score)?

US credit (some lenders may require 1 or 2 credit scores to qualify you).

This information can be overwhelming, but I recommend looking for the following items:Credit Score: Depending on your criteria, you may establish a minimum credit score for your tenants.

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

Walking score of 95.Pre COVID rental numbers:Monthly gross rent $15,250Cap rate 7.1%Future rental numbers:Estimated Monthly gross rent after current tenants move out $13,950Cap rate 6.5%Because monthly rent looks to be about 20-30% more if you rent by the month, I am considering renting out my duplex for monthly rentals on Airbnb/other sites and potentially for travel nurses (ideal because several hospitals are walking distance to my house).

I have mlo in Oregon and it’s the division of consumer finance and corporate securities. ca probably has a version of thathowever I did all my loans with my ca brokers license  

It has a free version and in the event you'd like to upgrade once you obtain more properties, the monthly cost is extremely reasonable. 

I’ve edited this version to comply with the rules and removed any references that could be perceived as self-promotion.
